Macular edema Classification and external resources

ICD-10	H35.8
ICD-9	362.01, 362.53

Macular edema occurs when fluid and protein deposits collect on or under the macula of the eye, a yellow central area of the retina, causing it to thicken and swell. The swelling may distort a person's central vision, as the macula is near the center of the retina at the back of the eyeball. This area holds tightly packed cones that provide sharp, clear central vision to enable a person to see form, color, and detail that is directly in the line of sight.

Cystoid macular edema is a type of macular edema that includes cyst formation.
